This cherry-picks upstream eb9bec0a5d
The current value causes significant artificial slowdown during mass
parallel file removal, which can be observed both on FreeBSD and Linux
when running real workloads.
Sample results from Linux doing make -j 96 clean after an allyesconfig
modules build:
before: 4.14s user 6.79s system 48% cpu 22.631 total
after: 4.17s user 6.44s system 153% cpu 6.927 total
FreeBSD results in the ticket.
See https://github.com/openzfs/zfs/issues/13932
The breakage was introduced in OpenZFS commit 48cf170d5.
When a (different) fix solving this issue gets upstreamed
it will replace the current fix in the next merge from OpenZFS.

We don't need the compress rotuines, nor zstd_opt.c. Remove them.
Expand the number of places we omit code for IN_LIBSA (which are FreeBSD
specific). Due to the agressive optimization, though, this doesn't
reduce the size of the loader. It does reduce the number of 'false
positives' for places to omit to reduce the size as well as reducing the
build time slightly.

OpenZFS commit: a86e089415
First open locking changes were correctly applied to zvol_geom_open but
incorrectly applied to zvol_cdev_open, causing spa_namespace_lock to be
held indefinitely.
Make the first open locking in zvol_cdev_open match zvol_geom_open.
This change has been accepted upstream in openzfs/zfs#13016 but is not
yet merged.

This reverts commit 5eb81a4b40, reversing
changes made to c6806434e7 and
this reverts commit 679ff61123.
What happend is git rebase --rebase-merges doesn't do what is expected.
The cookies argument is only used by the NFS server. NFSv2 defines the
cookie as 32 bits on the wire, but NFSv3 increased it to 64 bits. Our
VOP_READDIR, however, has always defined it as u_long, which is 32 bits
on some architectures. Change it to 64 bits on all architectures. This
doesn't matter for any in-tree file systems, but it matters for some
FUSE file systems that use 64-bit directory cookies.

When rolling back a dataset, ZFS has to purge file data resident in the
system page cache. To do this, it loops over all vnodes for the
mountpoint and calls vn_pages_remove() to purge pages associated with
the vnode's VM object. Each page is thus exclusively busied while the
dataset's teardown write lock is held.
When handling a page fault on a mapped ZFS file, FreeBSD's page fault
handler busies newly allocated pages and then uses VOP_GETPAGES to fill
them. The ZFS getpages VOP acquires the teardown read lock with vnode
pages already busied. This represents a lock order reversal which can
lead to deadlock.
To break the deadlock, observe that zfs_rezget() need only purge those
pages marked valid, and that pages busied by the page fault handler are,
by definition, invalid. Furthermore, ZFS pages always transition from
invalid to valid with the teardown lock held, and ZFS never creates
partially valid pages. Thus, zfs_rezget() can use the new
vn_pages_remove_valid() to skip over pages busied by the fault handler.

This reverts commit 59eab1093a.
The change suppressed EFAULT originating from uiomove(). The deadlock
avoidance mechanism implemented by vn_io_fault1() in the VFS handles
such errors by wiring the user pages and retrying, but this change
caused read() to return early instead. This can result in short I/O,
causing misbehaviour in some applications, and possibly other
consequences.
Until this is resolved somehow, revert the commit.
